StrikeIron’s Web Services Analyzer is a free Windows-based tool that allows anyone to quickly and easily understand any SOAP-based Web service – with the click of the mouse!

The Web Service Analyzer allows you to quickly and easily: * View the Web service inputs in a graphical tree-like structure * Enter inputs and execute the web service * See the results in a tabular spreadsheet format * View the SOAP Request and Response messages in XML format

The Analyzer executes the Web service dynamically. Then automatically parses the Web Services Description Language (WSDL) to determine the data requirements, data structure, and expected behavior of the Web service. You only need the URL to the WSDL document. No additional software or compiling is required.

JWebUnit is a Java framework that facilitates creation of acceptance tests for web applications. It evolved from a project where we were using JUnit to create acceptance tests. Also, we can have different testing engines. Currently, only HtmlUnit plugin is ready. As the tests were being written, they were continuously refactored to remove duplication and other bad smells in the test code. JWebUnit is the result of these refactorings. JWebUnit provides a high-level API for navigating a web application combined with a set of assertions to verify the application's correctness. This includes navigation via links, form entry and submission, validation of table contents, and other typical business web application features. This code try to stay independent of the libraries behind the scenes. The simple navigation methods and ready-to-use assertions allow for more rapid test creation than using only JUnit and HtmlUnit. And if you want to switch from HtmlUnit to the other soon available plugins, no need to rewrite your tests.

Browsershots makes screenshots of your web design in different browsers. It is a free open-source online service created by Johann C. Rocholl. When you submit your web address, it will be added to the job queue. A number of distributed computers will open your website in their browser. Then they will make screenshots and upload them to the central server here.

SproutCore is a framework for building applications in JavaScript with remarkably little amounts of code. It can help you build full “thick” client applications in the web browser that can create and modify data, often completely independent of your web server, communicating with your server via Ajax only when they need to save or load data.

SmartGWT is a GWT based framework that allows you to not only utilize its comprehensive widget library for your application UI, but also tie these widgets in with your server-side for data management. SmartGWT is based on the powerful and mature SmartClient library.

The Play framework makes it easier to build Web applications with JavaDiscover a clean alternative to bloated enterprise Java stacks. Play focuses on developer productivity and targets RESTful architectures

Capybara aims to simplify the process of integration testing Rack applications, such as Rails, Sinatra or Merb. Capybara simulates how a real user would interact with a web application. It is agnostic about the driver running your tests and currently comes bundled with rack-test, Culerity, Celerity and Selenium support built in.

Knockout is a JavaScript library that helps you to create rich, responsive display and editor user interfaces with a clean underlying data model. Any time you have sections of UI that update dynamically (e.g., changing depending on the user’s actions or when an external data source changes), KO can help you implement it more simply and maintainably.
